Are you proposing switching all tests to dejagnu starting with LIMIT, or 
using the LIMIT tests to experiment with dejagnu to determine if we want 
to move all our tests over?  I haven't used dejagnu, but from what I 
briefly read of the manual it seems like it will fit most of our needs.  
I have a concern about win32 compatibility.  The manual said to install 
cygwin to use dejagnu on NT.  Is this true for all our win32 platforms 
(did I mis-read it)?  Is this something we are willing to accept?  I 
know we moved the build process away from using cygwin type tools.  How 
about testing?  Either way I'm sure it would work out better than TCS.
